Crystal Structures of Anhydrous Rare-Earth Chlorides

The crystal structures at 298°K of LaCl3, NdCl3, EuCl3, and GdCl3 have been refined by full-matrix least-squares methods using three-dimensional MoKα intensity data. These isomorphous compounds belong to the UCl3-P63 / m structure type; metal atoms occupy symmetry sites at (13, 23, 14) and chloride...

Description
Summary:The crystal structures at 298°K of LaCl3, NdCl3, EuCl3, and GdCl3 have been refined by full-matrix least-squares methods using three-dimensional MoKα intensity data. These isomorphous compounds belong to the UCl3-P63 / m structure type; metal atoms occupy symmetry sites at (13, 23, 14) and chloride ions lie on mirror sites at (x, y, 14) with x≅0.39 and y≅0.30. Standard deviations of the interatomic separations do not exceed 1 part in 1000.
